WINDOW-CONTROLLING DEVICE.

Application filed November 20, 1920. Serial No. 425,312.

To all whom it may concern/.1

Be it known that I, JOHN D.'LA\VRENCE, a citizen of the UnitechState's of America, residing at Dura h/Iechanical Hardware 00., in the city of Toledo and State of Qhio,

have invented certain new" and useful Improvements in WVindow Controlling Devices, of whiclrthefollowing is a specification, reference being had therein to the accompanying' drawings. I j

' Thisinvention relatesto window-controlling devices and more particularly to devices for controlling the raising, lowering and locking of sliding windows in motor Vehicles. p

The invention consists in the structural features and arrangement of parts hereinafter fully set forth. In the drawings j Figure 1 is an interior view of a motor vehicle door provided with a window equipped with a controlling device in accordance with the. invention.

Figure 2 is a perspective view of the stem through which the window member is actuable vertically, showing the means associated with said stem for lockingthewindow in various positions of vertical adjustment. Figure 3 is a cross section taken on lines 3 3 of Figure l and illustrating the con trol means.

Figure 4 is a fragmentary perspectlve View of the actuating handle and locking head which is carried by said stem.

In these views the reference character A designates a. motor .vehiclefdjoor having in its upper portion a Window opening B and having its lower portion chambered as indicated at B. The closure for the opening B is formed by a vertically slidable plate of glass 0 which in lowered position is adapted to enter the chamber B. As is customary, there is provided suit-able meansicounter-balancing the weight of the glass plate C, this means consisting preferably of a pivotal arm D'bearing upwardly at its free end upon the lower. edge of said plate and urged upwardly by a coiled spring E, tensionedto exert the proper counter-balancing effort. The bottom edge of the glass plate 0 is permanently engaged by a strip F, the sides of which are cut away at one end of said strip to form the terminal tongue G to which is secured the lower extremity of a vertical actuating stem H.

Said stem extends freely upwardly within a tubular member I, preferably formed of sheet metal and longitudinally slotted as indicated at I. Said member is secured to the door A'at one side of thewindow opening B by screws I and is shaped to serve as a trim stick for the window. One margin of the slot 1" is flanged inwardly as in dicated at J and said flange is formed with a series of notches K. Upon the upper end of the stem H there is mounted a combined handle and locking member comprising a sleeve L rotatable upon said stem and formed with the radially projecting lug M adapted for locking engagement with any one of the notches K, when said sleeve is in the rotative position shown in full lines in Figure 3. A coiled spring N embraces the stem'H-within said sleeve urging the same into normal engagement with one of the notches K, said spring having one extremity anchored in the stem H and having its other end bearing against one end of a circumferenti'ally extended slot O-in said sleeve (see Figs. 3 and 4:). Said" sleeve is restrained from vertical movement upon the stem H by a pin P projecting from thestem into the slot 0. Q designates a handle member integral with the sleeve L and projecting radially therefrom through the slot 1.

Considering now the operation of the described invention, when it is desired to vary the position of adjustment of the window member C the handle Q is rocked from the position shown in full lines in Fig. 3 to the dash line position illustrated in the same figure. The sleeve L is thus rocked upon the stem H through'a sufficient angle to dis engage the lug M from the notched flange J, said lug assuming the dash line position shown in Fig. 3. By exerting pressure upwardly or downwardly upon the'handle Q, the stem H and window member C may now be adjusted upwardly or downwardly to any desired position. When thehandle member Q is released the spring N rocks the sleeve L to its normal position engaging the lug M with one of the notches K and thereby maintaining. the desired adjustment-of the window member. I

It is'a feature of the described invention that the tubular member I not only provides a casing or housing for the stem H and a locking element co-acting with the head of said stem' to hold the latter and window tu'dinally member properly adjusted, but further functions as a i for the window, By forming thelocklng notches in the flange J disposed interiorly of the tubular member I, said flange and notches are concealed and do not detract from the pleasing appearance of the trim stick. a 1 V e The inwardly projecting flange J, in addition to forming a latch element, further functions as a guide for the stem H restraining said stem against lateral swinging about its sup-ported lower end. i "What I claim as my invention is;

1; In a window control mechanism, the combination with "a slidable window meme ber, ofja stem secured to saidmember, a

locking head carried by said stem and adapted "to rock thereon, a co-acting tubular look ing member enclosing-said stem and longitudinally slotted, and. inwardly flanged marginal tosaid slot and formed upon said flange with a series ot'notches engageable by said-loeking-head inone position of its rookingmovement, saidih'ead' including a handle the longitudinal slot inthe tubular member.
